Stable and efficient organic light-emitting diodes were prepared using tetradentate platinum-based blue and red emitters. In one example, a series of stable and efficient red phosphorescent OLEDs was fabricated employing a phenyl-pyridyl-carbazole based tetradentate cyclometalated Pt(II) complex as an emitting dopant and utilizing a commercially available host, transporting, and blocking materials. By implementing this platinum complex in electrochemically stable device architectures, long operational lifetimes were achieved with an estimated LT97 of over 600 hrs at luminance of 1000 cd/m2.
Carbazolyloxyacetohydroxamic acid (1), 9,9′-decamethylene-bis-carbazolyloxyacetohydroxamic acid (2), benzohydroxamic acid (3) and acetohydroxamic acid (4) without reducing agent under aerobic conditions induced Col E1 DNA strand scissions with increasing of the activities in the order of 4 > 3 > 2 > 1. Inhibition experiments indicated that hydrogen peroxide and superoxide participated in the reactions
咔唑基氧基乙酰异羟肟酸 (1)、9,9'-十亚甲基-双-咔唑基氧基乙酰异羟肟酸 (2)、苯异羟肟酸 (3) 和乙酰异羟肟酸 (4) 在有氧条件下不使用还原剂诱导 Col E1 DNA 链断裂,其中活性增加4 > 3 > 2 > 1 的顺序。抑制实验表明过氧化氢和超氧化物参与了反应,但羟基自由基或单线态氧没有参与。
Color-tuning Pt(<scp>ii</scp>) complexes for natural-light electrophosphorescence
Efficient and durable OLEDs of cyan, greenish yellow, yellow and white colors were fabricated in simple structures with Pt–Cpy bonded complexes, giving state-of-the-art tuning the color of electroluminescence.
